• Collection of action spectra for photobiological effects induced by UV radiation and selection of representative action spectra.
• Derivation of requirements for ancillary data collection, reconstruction, climatology and trend analysis.
• Recommendation of biological action spectra, time resolution and other requirements for UV modelling.
• Dissemination of information on the biological importance of effective UV radiation and gained results to a broader audience.

Setteld Tasks

1. Questionnaire to evaluate which action spectra are mainly used in Europe (June 2004)
This questionnaire is still valid and answers are still welcome.
